The best is if you one of those little personal computer game / tv sets on each seat.. That always seems to make time fly! Otherwise, magazines, books, music, movies and sleep are about all that can be done. If you're flying with someone, a deck of cards or magnetic scrabble or something similar could help as well. Just be sure to stretch your legs regularly.

Some people recommend staying awake as long as you can before your flight so you're really really tired and have a bit more chance of sleeping. I'm usually too excited to sleep but then never flown further than 3 hours!

I'm hoping there's a good film, and choosing a good book beforehand. I like to sit by the window and wonder what I'm flying over- but not if its just water!

You're supposed to stretch the legs a bit on a long haul flight and exercise to avoid DVT aren't you. I guess however good your book is you're going to get a bit bored at some time!

The one thing i'm dreading about my trip is the long flight. Longest flight i was on before is 4 hours, and i thought that was terrible! I'll just have to keep reminding myself that its beats sitting in my office working. I'm hoping a good book will keep me going for most of the flight

Gotta agree with all of you. Books, magazines, cards, and most important for me is music. I HAVE to have my CD player with me at all times, with a multitude of CDs. If you have an iPod/any other mp3 player, you get by without the extra baggage of CDs. But music is super important, and worth the extra weight.

I love those flights where you have your personal tv and you can choose your movies, tv reruns, games, music, etc. They help pass the time really well. And I know this doesn't happen as a rule, but you never know who you sit next to, and if your lucky, they might just be an interesting talker. I sat between an old German lady who was a devout Christian, and a Christian Scientist once. Our conversation was flowing and quite interesting until the old lady made a comment about Scientology. They didn't get all testy or anything but a really interesting debate ensued that made hours pass in a snap.

Basically keep in mind that the carry on bag is an important remedy for boredom!

NORWALK, Conn., Oct. 1 /PRNewswire/ -- Virgin Atlantic is delighted to announce the introduction of double suites for passengers traveling in the award winning Upper Class Suite. The airline has fitted four pairs of double suites onto two of its Boeing 747-400 aircraft, giving passengers traveling together two square meters of space so that they can enjoy their flight closer together.

"The award winning Upper Class Suite provides the passenger with by far the longest and most comfortable bed flying in the air today and now passengers can enjoy even 'suiter' dreams next to their loved ones!"

Music is my number one as well. Music and books. And also, it doesn't hurt to do the sleep thing in combination, and completely tire yourself out beforehand and try to sleep as much as you can on the plane. This helps with jetlag too if you're going to switch time zones drastically. And yeah, walk up and down the plane as much as possible too.
